can I regenrate initial conditions in the 48-pulse GTO STATCOM after changing frequency from 60Hz to 50Hz

I was trying to change frequency from 60Hz to 50Hz of a model of 48 pulse GTO STATCOM. But that is not working. How can I change frequency for it?

Hello Shivam,

what version are you using? I modified the PLL to 50 hz and then changed all of the transformers to 50 hz and it works.

I am using R2019a model. Can you please tell me steps to do that change?

[Joel Van Sickel]

Sure thing Shivam,

you need to change all your power system components to be 50 hz, so the sources and loads. Then you need to change the transformers inside your 48 pulse GTO inverter. The final step is to go into the contrroller and find the PLL and change that to also be 50 hz.

Sir, do I need to regenerate initial condition after doing this because I am still getting the same error.

[Joel Van Sickel]

what is the error?

[Shivam Singh]

Sir, I am not getting any error but the waveforms are not correct.
